--- Comment #3 from Stefan <pralltgaranti...@flusskilometer.de> ---
I can reproduce, especially comment 1:
Kleopatra
Version 2.2.0-gitfb4ae3d (2015-11-12)
Unter KDE 4.13.3
on Windows 10 64bit (Pro), should be up to date as of 2017-01-17
Intel Core i5-4670K @ 3.4 GHz

sha256sum.txtHp2692.new
sha1sum.txtHp8528.new
are generated for a 3.91 GB large file (4102945 KB), moving file to
sha256sum.txt failed: Error renaming the file.

Unfortunately the executables seem single threaded. Running "sha256sum.exe
filename.iso" directly in the windows commandline gives me a checksum after 42
seconds. So it is difficult to look for a timeout. One core of my system is on
100% load. Moving the large file to an SSD does not speed this up. So I can't
easily test if it is a time out or a file size problem.

>From a 1.67 GB (1758561 KB) large file the checksums are correctly calculated
and saved.
>From HDD:
sha256sum.exe has a run time of ~19 seconds
>From a USB thumbdrive on USB3: 19 seconds
Same drive on USB 2: 44 s
Kleopatra on USB 2: could not move file after 32 seconds

But Window's USB-File-Caching let's me successfully finish a second run on the
same file in under 30 seconds. (To avoid the use of cached thumbdrive data, I
did my test always on a freshly plugged in drive and verified the read speed in
the Windows Resource Monitor.)
